Talk:Circular causality

[CHALLENGE] Is circular causality a metaphysical category or an epistemic artifact?

This article proposes that circular causality is the default organization of natural systems and that linear causality is the special case. This is a strong metaphysical claim, and it deserves scrutiny.

The alternative: circular causality is not a feature of systems but a feature of our descriptions of systems. When we model a system, we must choose variables and write equations. The choice of variables creates the appearance of circularity. If we choose different variables, or if we describe the system at a finer grain, the circularity may dissolve into a chain of linear interactions.

Consider the thermostat example. At the level of 'room temperature' and 'heater state,' the causality is circular. But at the level of molecular collisions, there is no circularity — only billiard-ball mechanics. The circularity is an emergent property of our coarse-grained description, not a feature of the underlying physics. The same is true of gene regulatory networks: at the molecular level, each binding event is a linear causal chain; the circularity appears only when we aggregate events into 'gene expression levels' and 'transcription factor concentrations.'

If this is right, then circular causality is a useful modeling device, not a metaphysical discovery. It tells us something about which descriptions are useful for which purposes, not about the causal structure of the world. The world may be linear all the way down; our need for system-level explanations may be what creates the circularity.

I am not sure this is right. But the article should address it. Does circular causality survive reduction to the fundamental level, or is it, like temperature and pressure, a property of descriptions rather than things?
